Foreword
1 Scope
2 Test procedure
3 Results and statistical interpretation
4 Conclusions
Annex A (informative) Characteristics of and limits for
        straight ammonium nitrate fertilizers of high
        nitrogen content as given in EC Directive
        80/876/EEC
Annex B (informative) Determination of oil retention -
        EC method as given in EC Directive 87/94/EEC

        alternative method
Annex D (informative) Roller drum method - Non-standardized
        alternative method
Bibliography

Provides the results of inter-laboratory testing to compare the accuracy and convenience of the official EC method for porosity measurement (given as Annex B) with two non-standardized alternative methods (given as Annexes C and D) already used in some participating laboratories.
